the deck plates are secured together by over-- Other beams 5 of different heights may be located each side of the keelson to provide supports for the interior snperstructure'of the boat,

The deck, or top of the hall is formed by assembling the channel plates or beams 15', with their flanges l6, abuttin as shown in Figs. 1 and 2. These plates w ion assembled are arranged. end to end, the flanges extending inwardly, and the latter are riveted together as indicated at 1?", the outermost flanges 18 of the outside plates 15 being riveted to the upper end of the side plates 1, The adjacent flanges and ends of lapping plates 20?. The flanges 16, provide not only a means for securing adjacent channel plates together, but in :uhlition thereto, they produce a plurality of reinforcing longitudinal ribs, pi using a strong and stable deck; TLtllCtUl'fi. o furtheii' strengthen the dock structure formed by the plates 15, I provide a series of I beams ill, under the ribs or flanges ill, and may be secured tothe latter by overlapping metal plates 23. The joints of the deck are-calked to make the same Water tight.

By dispensing; with a flange, or rib at one edge of each plate, the 0\'8Illt} )lllg oi two ad acent plates occurs opposite to the rib oi: flange on nest succeeding plate, as shown in Fig. The overlapping portions of the plates; when arranged as shown in this figure will be rivw on both sides of the rib 2*; Thus the structure is'doubly reinforced throughout its entire length.

By constructing a bull, or compartment, or other structure, in the i'nanner described, it will be obvious the same is extremely economical as it is not necessary to provide a separate super-structure. The flanges or ribs of "the plates 1 and serve to brace the hull, in precisely the same manner as if applied in separate pieces. It may be stated as a fact, that flanges made integral with the plates possess decided advantages over :separate pieces, inasmuch as liability to break or separation between the braces and plates is impossible. Furthermore, the lappingot the plates at points adjacent the flanges or ribs, adds materially to strengthen the structure, and reinforces the flanges.

It will be obvious, i may arrange the plates so that they may overl j) each other in vertical alineiuent, as shown in Fig. 6, rather than in horizontal alinement, as shown in the other figures the drawing.

The keelson may be formed by placing beams of different height, end to end, as shown in, Fig. 7. It is essential to make the keelson' heavier where the engines, or other heavy mechanism is supported in the hull of a boat, and so far as I am aware, here-- tofore 1t has been necessary to build up beam for this purpose. But I find that I of plates havin integral ribr can accomplish the desired result by tying together two or more beams, 6 each ot' dit ferent height, and each being formed in. a separate piece. A. hull of a boat made up of plates beams, in addition to strength, posse lightness, as the interior superstructin'i: usually employed is entirely dispensed with.

The plates may be of any conven' ut width, length and thiclmess, depending :iitirely upon the ch rector of the structure formed;

What I claim is:

#1. A compartment formed oil a plurality of plates havin integral ribs, the edges of said plates overlapping the edges of the Ml-- jacent plates, means for securing the oven lapping portions of the plates together, the other edges of the plates abutting against the edges of the plates adjacent thereto, the 3 ribs of the adj aeent plates whose edrv being in alincment. to.provide in the compartment and a bee: 'locat bottom of the compartment- LLl overiamiin the meeting edges of the plates,

3. A coinpartment'formed on. its sides and bottom by a plurality of plat trained with ribs, the adjacent ed es of said plates overlapping at points adjacent the ribs, rivets securing the overlapping portionsel" the plates, the other edges of the plates fnittiug against c2105? other and,tho ribs forming continuous rei forcing braces on the inside of the. compartment, plates OVUIlQt'JlIQlIIg the edges of. the plates which abutzlgu 'nst each other, rivetssecuring the latter plates, 21 sories of channel beams forming the top of the compartmentgthe flanges of the'clnumel beams a utting and forming reinforcingribs throughout the length of thecompartment, and rivets securing the said latter flanges together.

5.'A compartment. formed of a series of mime on the uppermost side plate overlapping and being riveted to the end channel plate.
